I plan to testfire tomorrow.  I'll see if the 1896 rear sight will work with commercial ammo and my reloads.  If so I'll make a piece to fit that big dovetail and tap a hole in it for the rear sight screw to engage.  There's only 1 thread left in the bottom of the rear hole right now.
I would like to put a Pacific or Redfield no-drill on my rifle.  An aperture sight would be much easier for me to use.  But because I couldn't resist buying this second sporter Krag now my budget is shot, at least for the time being. ;)
